A processor communication register (PCR) contained in each processor
within a multiprocessor cluster network provides enhanced processor
communication. Each PCR stores identical processor communication
information that is useful in pipelined or parallel multi-processing.
Each processor has exclusive rights to store to a sector within each PCR
within the cluster network and has continuous access to read the contents
of its own PCR. Each processor updates its exclusive sector within all of
the PCRs via a private protocol or dedicated wireless network, instantly
allowing all of the other processors within the cluster network to see
the change within the PCR data, and bypassing the cache subsystem.
Efficiency is enhanced within the processor cluster network by providing
processor communications to be immediately networked and transferred into
all processors without momentarily restricting access to the information
or forcing all the processors to be continually contending for the same
cache line, and thereby overwhelming the interconnect and memory system
with an endless stream of load, store and invalidate commands.
